3/// Withdraw liquidity from a position in the Whirlpool. This call also updates
4/// the position's accrued fees and rewards. ### Authority
5/// - `position_authority` - authority that owns the token corresponding to this
6///   desired position.
7///
8/// ### Parameters
9/// - `liquidity_amount` - The total amount of Liquidity the user desires to
10///   withdraw.
11/// - `token_min_a` - The minimum amount of tokenA the user is willing to
12///   withdraw.
13/// - `token_min_b` - The minimum amount of tokenB the user is willing to
14///   withdraw.
15///
16/// #### Special Errors
17/// - `LiquidityZero` - Provided liquidity amount is zero.
18/// - `LiquidityTooHigh` - Provided liquidity exceeds u128::max.
19/// - `TokenMinSubceeded` - The required token to perform this operation
20///   subceeds the user defined amount.
